Question

A loaded sack of mass 100kg falls down from the floor of a lorry 2m high. Calculate the work done by gravity on the load (g=10mls2)

Answer 1

Explanation:

MASS-100KG(GIVEN)

HEIGHT-2M

ACCELERATION DUE TO GRAVITY=10M/SO

THEREFORE,

BY USING THE FORMULA OF POTENTIAL DIFFERENCE,

WE GET,

MASS×GRAVITY FORCE×HEIGHT

SO,

100×10×2

2000Joules.
